3:10 PM | Study: Sequence & Phylogenetic Analysis Of Emerging H9N2 influenza Viruses In China
Poultry Vaccination - Photo Credit OIE   # 8425   Among the avian flu viruses we watch with concern, the H5N1 and H7N9 viruses have gained the most notoriety.  Yet, behind each of these rising stars is an unindicted co-conspirator – the ubiquitous, but little noticed H9N2 avian virus – which has lent crucial internal genes to both of these emerging threats. We looked at these contributions six weeks ago in The Lancet: H9N2’s Role In Evolution Of […]

12:47 PM | USGS Warns On Fake Earthquake Alert
Earthquake Hoax warning from the USGS   #8424   With a couple of medium-sized temblors in Los Angeles in recent weeks, an ongoing swarm of quakes in Oklahoma, and another medium-sized temblor last week in Yellowstone, I guess it was inevitable that the prognosticators of perpetual doom on the internet would begin to predict that California was about to fall into the Pacific, or that the Yellowstone Supervolcano would destroy the North American continent.   These are […]

9:37 PM | PNAS: Testing An IL-15 Adjuvanted Vaccinia-Based `Universal’ Flu Vaccine (In Mice)
    # 8422   The headlines this afternoon – particularly those coming out of Hong Kong – are proclaiming a `Breakthrough’  that may eventually  lead to a universal flu vaccine.  The key word is `eventually’, as so far this breakthrough has only been tested in mice . . . and as we’ve seen before in medical research, mice are sometimes terrible liars.   The excitement is over a study, published yesterday in PNAS,  […]

7:05 PM | This Month In Blastocystis Research (MAR 2014)
If there's one paper that really made my eye balls pop over the past 30 days, it's the paper appearing a couple of days ago in BMC Infectious Diseases by Safadi et al. on Blastocystis in a cohort of Senegalese children. The paper is open access and can be downloaded here. But I'll be jumping right at it:A 100% prevalence of Blastocystis in a cohort of 93 Senegalese children! The children represented a mixed group of children with and without symptoms. And yes, they were all […]

Collaboration – when scientists come together to share knowledge and know-how in order to tackle complicated problems, answer tough questions and develop big new ideas – is one of my favorite parts of the scientific process.

In a fascinating post by Virginia Hughes, “The Humble Heroes of Weight-Loss Surgery: Stomach Acids and Gut Microbes”, she writes about a recent study working to tease apart the factors that make weight-loss surgery effective. The authors essentially find that it’s not the physical alteration that matters, but rather an increase in bile acids and changes to the gut bacterial community that provide the beneficial effect. There’s some great info in the post on how and why […]
